According to Steve Squyres' latest journal entry, Opportunity is now seeing virtually -no- blueberries in the surface matrix anymore.
"...On top of that, Opportunity has stumbled onto something really new and different lately... the blueberries seem to be gone!..." And a theory: "But one possible guess at this point is that we have moved "up section" in geologic terms -- to rocks that are higher up in this stack of layered sediments -- and that the rocks at this level never experienced the concretion-forming process. It's an interesting hypothesis with interesting implications, and it's also one that could explain a few other odd things we've been thinking about ever since Eagle crater" Looks like Oppy will stop for some intense IDD work in the next day or so. |

"All I can guess is that they figured out what they are in the initial investigation a while back, and they decided to only tell us what they are not." I think it's much more likely that they have NOT figured out what they are. The cobbles are clearly different, but the team doesn't understand them yet. They need more data, which might be found at Payson. There has been no shortage of discussion of different rock types at Gusev in recent months.
